This product had no reviews so I was a bit dubious about buying them. In the end I was so intrigued by the look of them and the low price that I took a punt.
They fit into my ears well. I sometimes fall asleep to audiobooks and these in-the-ear jobs are ideal for that as they fit flush to the ear and have a durable-looking cable. Of course these 'phones look much, much cooler than my naff Philips SBCHL145's. Build quality looks good enough.
They are LOUD. I had to turn my computer volume way down from normal and also use the volume sliders on the various programmes I use them for (Windows Media Player, iTunes, DVD player, iPlayer etc) in order to get the volume down to a comfortable level.
The sound quality is difficult to judge. The listening experience is very different to my old faithful lightweight over-the-head 'phones (Philips SBCHL145/10). To my ears the new ones sound a combination of bassy and echoey but most of all the music sounds 'far away'. I'm not sure how much this is down to the phones themselves and how much to the fact that they are ear-canal type headphones: this is my first experience with deep-in-the-ear jobbies and I can't work out if the sound quality is low or just different.
Because I prefer my over-the-head 'phones I haven't used them much and, in fact, ended up giving them away to a friend who needed a pair to use in the gym. She LOVES them.
I'm currently listening to music on a pair of Sony Ericsson in-the-ear MH650's that I found in an old mobile phone box and they have a similar 'far-away' sound to the red ones under review, so maybe that IS a feature of the design. Without trying a much more expensive pair of in-the-ear 'phones I suppose I'll never know.
In short; I'm sticking to over-the-head style but they get four stars because of my friend's rave review.
